In some related arts, functional elements such as the front camera andIR hole are provided under the screen of a full-screen mobile phone.After research, the inventor has found that the screens in the relatedarts are inadequate in the light transmittance, which may affect theoptical signal reception of the under-screen functional elements to acertain extent.

In view of this, embodiments of the present disclosure provide a pixelarrangement structure, a display panel, and a display device, which canimprove the optical signal reception of the under-screen functionalelements.

FIG. 1 is a schematic structural view according to one embodiment of adisplay device of the present disclosure.

Referring to FIG. 1, in some embodiments, the display device includes adisplay panel 3 and a functional element 4. The display panel 3 includesa specific pixel arrangement structure including a first pixel area Land a second pixel area H adjacent to each other. The first pixel area Land the second pixel area H adjacent to each other means that thedistance between the edge of the first pixel area L adjacent to thesecond pixel area H and the second pixel area H is smaller than theheight of the sub-pixel in the first pixel area L along a columndirection. In FIG. 1, a major part of the display panel 3 is a secondpixel area H, and the first pixel area L is located at an upper edge ofthe second pixel area H.

The functional element 4 can be located on an opposite side of the lightemitting side of the display panel 3, and the light receiving surface ofthe functional element 4 corresponds to the first pixel area L in thepixel arrangement structure of the display panel 3, and is configured toreceive an incident light from the light emitting side of the displaypanel 3.

The functional element 4 can include a camera element, such as a frontcamera of a mobile phone. The functional element can also include an IRelement, a reflective induction element, or an ambient light sensor. Thefirst pixel area L and the second pixel area H can display an image, andthe functional element can also receive the incident light from theoutside of the display panel through the first pixel area of the displaypanel 3.

In order to increase the light transmittance of the first pixel area L,the first pixel area L can be made to have a pixel density lower than apixel density of the second pixel area H. Therefore, according toembodiments of the present disclosure, the first pixel area and thesecond pixel area adjacent to each other respectively include pixelgroups in different arrangement manners, and the first pixel area has apixel density lower than that of the second pixel area. In this way, onone hand, it is possible to reduce the light emitting area of the firstpixel area, and increase the light transmittance, so that the functionalelement receives more light signals; on the other hand, it is alsopossible to simplify the design of the backplane circuit of the firstpixel area.

FIG. 2 is a schematic pixel arranging diagram according to oneembodiment of the pixel arrangement structure of the present disclosure.

Referring to FIG. 2, in some embodiments, the first pixel area Lincludes a plurality of first-category pixel groups 10. Sub-pixels ineach first-type pixel group of the first-category pixel groups 10 isarranged according to a first arrangement manner. The first arrangementmanner can be a Real arrangement (i.e., Real RGB). This arrangementmanner can include red (R) sub-pixels, green (G) sub-pixels, and blue(B) sub-pixels arranged in several arrays, and the sub-pixels havingthree different colors are crossed therebetween, to present a shapewhich is approximately a “delta shape”. The second pixel area H includesa plurality of second-category pixel groups. Sub-pixels in eachsecond-type pixel group of the second-category pixel groups is arrangedaccording to a second arrangement manner. The second arrangement manneris alternatively a Pentile arrangement, that is, a sub-pixel is added onthe basis of RGB to realize, for example, red, green, blue and green(RGBG), red, green, blue and white (RGBW), red, green, blue and yellow(RGBY), or the like. Moreover, partial sub-pixels in the Pentilearrangement are “shared”, thereby achieving a higher resolution than anactual resolution in a visual effect.

The first-category pixel groups 10 which uses a Real arrangement, canminimize a visual effect loss of the first pixel area L. Since the firstpixel area L has a pixel density lower than that of the second pixelarea H, compared to the use of a virtual resolution, the first pixelarea L having the pixel group which uses a real resolution can improve avisual experience of human eye. In addition, the number of sub-pixelshaving R and B colors in the Real arrangement manner is twice that ofthe Pentile arrangement manner. Therefore, at the same aperture ratio(i.e., the same brightness), each sub-pixel of the pixel group in a Realarrangement has a brightness half of that of each sub-pixel of the pixelgroup in a Pentile arrangement, and correspondingly has a requiredsub-pixel current also half of that in a Pentile arrangement, therebyreducing a service life attenuation rate of the sub-pixel.

In FIG. 2, the first pixel area L is adjacent to the second pixel areaH. The number of sub-pixels in the first pixel area L based on a Realarrangement along a row direction and a column direction is reduced by ½compared to the number of sub-pixels in the second pixel area H based ona Pentile arrangement, so that the pixel density of the first pixel areaL can be ½ of the pixel density of the second pixel area H. In otherembodiments, the ratio of the pixel density of the first pixel area L tothat of the second pixel area H can be 1/N, wherein N is an integergreater than 1. Here, the pixel density of the first pixel area L is adensity of actual pixels. Actual pixel refers to a physical pixel, thatis, the smallest physical unit capable of controlling display of thedisplay panel. The pixel density of the second pixel area H is a densityof virtual pixels. Virtual pixel also refers to as an intuition pixel,whose color is obtained by mixing a plurality of adjacent color pixels.The bright spots formed by the virtual pixel are scattered and locatedbetween various actual sub-pixels.

Referring to FIG. 2, in some embodiments, the first-category pixel group10 include a first sub-pixel 11 of a first color, a second sub-pixel 12of a second color, and a third sub-pixel 13 of a third color (differentcolors are distinguished by different filling patterns in the drawings).Lines connecting centers of the first sub-pixel 11, the second sub-pixel12, and the third sub-pixel 13 can form a triangle. In FIG. 2, the firstsub-pixel 11 in the first-category pixel group 10 is located on one sideof the second sub-pixel 12 and the third sub-pixel 13 away from thesecond pixel area H (i.e., an upper side of the second sub-pixel 12 andthe third sub-pixel 13 in FIG. 2).

In some embodiments, the first color is green, the second color is red,and the third color is blue to form the three primary colors of RGB. Inother embodiments, the first color is green, the second color is blue,and the third color is red. In other embodiments, the three colors canalso be other colors, such as cyan, magenta, and yellow, to form thethree primary colors of CMY.

A plurality of first-category pixel groups 10 are arranged in an array.The centers of the first sub-pixels 11 of each column of thefirst-category pixel groups in the first pixel area L are in a samestraight line. For an embodiment in which the first color is green,human eye is more sensitive to green sub-pixels. Therefore, when thegreen sub-pixels are linearly aligned along a column direction, thepixel arrangement within the first pixel area L can be more uniformvisually. In addition, the centers of the first sub-pixels 11 of eachrow of the first-category pixel groups 10 can also be in a same straightline, and the centers of the second sub-pixels and the third sub-pixelsof each row of the first-category pixel groups 10 can be all in the samestraight line. By aligning the first sub-pixels along a row direction ina straight line, with the second sub-pixels and the third sub-pixelsalso aligned in a straight line, the white point distribution formed bythe first-category pixel groups 10 can be more uniform, therebyimproving the display quality.

In FIG. 2, in each column of the first-category pixel groups 10 in thefirst pixel area L, the centers of the second sub-pixels 12 are in thesame straight line, and the centers of the third sub-pixels 13 are inthe same straight line. In this way, the second color and the thirdcolor within the first pixel area L can form a vertical line with afavorable consistency along a column direction, and the first sub-pixelsof the first color that also line up in the column direction, therebymaking the pixel arrangement of the first pixel area L along a columndirection and a row direction more uniform visually, and furtherimproving the display quality.

Referring to FIG. 2, in some embodiments, the second-category pixelgroups 20 include a fourth sub-pixel 21 of the first color, a fifthsub-pixel 22 of the second color, a sixth sub-pixel 23 of the thirdcolor, and a seventh sub-pixel 24 of the first color. Here, the firstcolor, the second color, and the third color can refer to the colors ofthe sub-pixels in the first pixel area L. For example, the first coloris green, the second color is red, and the third color is blue.

FIGS. 3 and 4 are respectively schematic pixel arranging diagrams ofpixel groups in odd-numbered rows and even-numbered rows in a seconddisplay area according to one embodiment of the pixel arrangementstructure of the present disclosure.

Referring to FIGS. 3 and 4, the second-category pixel groups 20 in theembodiment of FIG. 2 can be divided into a group of first pixels 20 aand a group of second pixels 20 b according to an arrangement manner ofthe sub-pixels. The plurality of second-category pixel groups 20 can bearranged in an array. The first pixels 20 a and the second pixels 20 bare both repeated along a row direction and arranged alternatively alonga column direction.

In FIG. 3, the fourth sub-pixel 21 of the first pixel group 20 a islocated on a left side of the sixth sub-pixel 23, the fifth sub-pixel 22is located on a right side of the sixth sub-pixel 23, and the seventhsub-pixel 24 is located between the fifth sub-pixel 22 and the sixthsub-pixel 23 and on a lower side of the fifth sub-pixel 22 and the sixthsub-pixel 23. In FIG. 4, the seventh sub-pixel 24 of the second pixel 20b is located on a lower left side of the fifth sub-pixel 22, the fourthsub-pixel 21 is located on a right side of the fifth sub-pixel 22, andthe sixth sub-pixel 23 is located on a right side of the fourthsub-pixel 21. In the first pixels 20 a and the second pixels 20 b, thefourth sub-pixel 21 and the seventh sub-pixel 24 are both in the firstcolor.

Referring to FIG. 2, in some embodiments, the centers of the firstsub-pixels 11 of each column of the first-category pixel groups 10 inthe first pixel area L and the center of one of the fourth sub-pixel 21and the seventh sub-pixel 24 of each column of the second-category pixelgroups 20 in the second pixel area H are in a same straight line. For anembodiment in which the first color is green, human eye is moresensitive to green sub-pixels. Therefore, when the green sub-pixels arelinearly aligned along a column direction of the first pixel area L andthe second pixel area H, the white lines within the first pixel area Land the second pixel area H adjacent to each other along a columndirection are more matched, so that the first pixel area L and thesecond pixel area H have a relatively smaller image change and offset,thereby enhancing the image quality.

FIGS. 5-8 are respectively schematic pixel arranging diagrams accordingto some embodiments of the pixel arrangement structure of the presentdisclosure.

Referring to FIGS. 2 and 5, by comparing the embodiment of FIG. 5 andthe embodiment of FIG. 2, the difference lies in that the firstsub-pixel 11 in the first-category pixel groups 10 in the first pixelarea L is located on one side of the second sub-pixel 12 and the thirdsub-pixel 13 adjacent to the second pixel area H (i.e., lower sides ofthe second sub-pixel 12 and the third sub-pixel 13 in FIG. 5). Thismakes the sub-pixels of the first pixel area L adjacent to the secondpixel area H to be the second sub-pixel 12 and the third sub-pixel 13,and the sub-pixel of the second pixel area H adjacent to the first pixelarea L to be the first sub-pixel 11, so that the sub-pixels of the firstpixel area L and the second pixel area H adjacent to each other havedifferent colors, thereby reducing or eliminating the color shift riskcaused by color accumulation of the second sub-pixel and the thirdsub-pixel at a boundary position of the two pixel positions, andenhancing the image quality.

Referring to FIGS. 2 and 6, by comparing the embodiment of FIG. 6 andthe embodiment of FIG. 2, the difference lies in that the first-categorypixel groups in odd-numbered and even-numbered rows in the first pixelarea L have different arrangement manners. In FIG. 6, positions of thesecond sub-pixel 12 and the third sub-pixel 13 in the first-categorypixel groups 10 a in the odd-numbered rows with respect to the firstsub-pixel 11 are different from the positions of the second sub-pixel 12and the third sub-pixel 13 in the first-category pixel groups 10 b inthe even-numbered rows with respect to the first sub-pixel 11. Thefirst-category pixel groups 10 a in the odd-numbered rows and thefirst-category pixel groups 10 b in the even-numbered rows are arrangedat intervals along a column direction. This pixel structure can make thefirst pixel area L form an alternating form of the second sub-pixel 12of the second color and the third sub-pixel of the third color along acolumn direction, which can reduce the color shift risk accumulated in asingle color, thereby enhancing the image quality.

In addition, referring to FIG. 6, in some embodiments, the centers ofthe second sub-pixels 12 of each column of the first-category pixelgroups 10 a or 10 b in at least partial rows in the first pixel area Land the fifth sub-pixels 22 in a corresponding column of thesecond-category pixel groups 20 in the second pixel area H are in thesame straight line. In this way, the first pixel area L and the secondpixel area H can form lines of a second color with relatively consistentshapes. Similarly, the centers of the third sub-pixels 13 of each columnof the first-category pixel groups 10 a or 10 b in at least partial rowsin the first pixel area L and the sixth sub-pixels 23 in a correspondingcolumn of the second-category pixel groups 20 in the second pixel area Hare in the same straight line. In this way, the first pixel area L andthe second pixel area H can have a relatively smaller image change andoffset, thereby improving the image quality.

In FIG. 6, the sub-pixels of the first pixel area L and the second pixelarea H adjacent to each other have different colors, so that it ispossible to effectively reduce or eliminate the color shift risk causedby accumulation of the sub-pixels having the same color at a boundaryposition of the two pixel positions, and enhancing the image quality.

Referring to FIGS. 5 and 7, by comparing the embodiment of FIG. 7 andthe embodiment of FIG. 5, the difference lies in that the first-categorypixel groups in odd-numbered and even-numbered rows in the first pixelarea L have different arrangement manners. In FIG. 7, the positions ofthe second sub-pixel 12 and the third sub-pixel 13 in the first-categorypixel groups 10 a in the odd-numbered rows relative to the firstsub-pixel 11 are opposite to the positions of the second sub-pixel 12and the third sub-pixel 13 in the first-category pixel groups 10 b inthe even-numbered rows relative to the first sub-pixel 11. Thefirst-category pixel groups 10 a in the odd-numbered rows and thefirst-category pixel groups 10 b in the even-numbered rows are arrangedat intervals along a column direction. This pixel structure can make thefirst pixel area L form an alternating form of the second sub-pixel 12of the second color and the third sub-pixel of the third color along acolumn direction, which can reduce the color shift risk of single coloraccumulation, thereby enhancing the image quality.

In addition, referring to FIG. 7, in some embodiments, the centers ofthe second sub-pixels 12 of each column of the first-category pixelgroups 10 a or 10 b in at least partial rows in the first pixel area Land the centers of the fifth sub-pixels 22 of the second-category pixelgroups 20 in a corresponding column in the second pixel area H are inthe same straight line. In this way, the first pixel area L and thesecond pixel area H can form lines of a second color with relativelyconsistent shapes. Similarly, the centers of the third sub-pixels 13 ofeach column of the first-category pixel groups 10 a or 10 b in at leastpartial rows in the first pixel area L and the center of the sixthsub-pixels 23 of the second-category pixel groups 20 in a correspondingcolumn in the second pixel area H are in the same straight line. In thisway, the first pixel area L and the second pixel area H can have arelatively smaller image change and offset, thereby improving the imagequality.

In FIG. 7, the sub-pixels of the first pixel area L and the second pixelarea H adjacent to each other have different colors, so that it ispossible to effectively reduce or eliminate the color shift risk causedby accumulation of the sub-pixels having the same color at a boundaryposition of the two pixel areas, and enhancing the image quality.

Compared with the above-described embodiments, referring to FIG. 8, insome embodiments, a plurality of eighth sub-pixels 25 of the first colorin the second pixel area can be provided adjacent to the first pixelarea L. The eighth sub-pixel 25 is located between the second sub-pixelin one of every two adjacent columns of the first-category sub-pixels inthe first pixel area and the third sub-pixel in another of every twoadjacent columns of the first-category sub-pixels in the first pixelarea. In FIG. 8, at a location where the first pixel area L is adjoinedwith the second pixel area H, the sub-pixels of the second color and thesub-pixels of the third color are present alternately, and thesub-pixels of the second color and the sub-pixels of the third color aremixed by adding the eighth sub-pixel 25, so that it is possible toeliminate a purple color bleeding risk at the adjoining location,thereby enhancing the image quality.

The eighth sub-pixel 25 can also be added to other embodiments. Forexample, in the embodiments of FIGS. 2 and 6, the eighth sub-pixel 25can be disposed at a position in the second pixel area H adjacent to thefirst pixel area L, and between the second sub-pixel and the thirdsub-pixel between every two adjacent columns of the first-categorysub-pixels in the first pixel area.

Referring to FIGS. 2 to 8, in some embodiments, the second sub-pixel 12,the third sub-pixel 13, the fifth sub-pixel 22, and the sixth sub-pixel23 all have a same shape, which is hexagonal. The first sub-pixel 11 isa hexagon, which has the same shape as that of the second sub-pixel 12and the third sub-pixel 13, but the shape of the first sub-pixel 11 isdifferent from that of the fourth sub-pixel 21 or the seventh sub-pixel24. The shapes of the fourth sub-pixel 21 and the seventh sub-pixel 24are pentagons with opposite directions respectively, and having an equalarea. The fifth sub-pixel 22 and the sixth sub-pixel 23 have an equalarea, and the fourth sub-pixel 21 has an area smaller than that of thefifth sub-pixel 22.

In above-described various embodiments of each pixel arrangementstructure of the present disclosure, the shapes and arrangement mannersof the sub-pixels in each pixel group are not limited to those shown inFIGS. 2 to 8, and other shapes and arrangement manners can also be used.

In FIG. 9, the first sub-pixel 11′ in the first-category pixelgroups 10′ is located on one side of the second sub-pixel 12′ and thethird sub-pixel 13′ away from the second pixel area H (i.e., an upperside of the second sub-pixel 12′ and the third sub-pixel 13′ in FIG. 9).

The first pixels 20 a′ and the secondpixels 20 b′ are both repeatedly arranged along a row direction, andarranged alternatively along a column direction.

In FIG. 10, the seventh sub-pixel 24′ of the first pixel 20 a′ islocated on a lower side of the fifth sub-pixel 22′ and the sixthsub-pixel 23′ and between the fifth sub-pixel 22′ and the sixthsub-pixel 23′, the fifth sub-pixel 22′ is located on a left side of thesixth sub-pixel 23′, and the fourth sub-pixel 21′ is located on a lowerright side of the sixth sub-pixel 23′. In FIG. 11, the fourth sub-pixel21′ of the first pixel 20 a′ is located on a lower side of the fifthsub-pixel 22′ and the sixth sub-pixel 23′ and between the fifthsub-pixel 22′ and the sixth sub-pixel 23′, the fifth sub-pixel 22′ islocated on a right side of the sixth sub-pixel 23′, and the seventhsub-pixel 24′ is located on a lower right side of the fifth sub-pixel22′. In the first pixel 20 a′ and the second pixel 20 b′, the fourthsub-pixel 21′ and the seventh sub-pixel 24′ are both in the first color.

FIGS. 12 to 15 are respectively schematic pixel arranging diagramsaccording to other embodiments of the pixel arrangement structure of thepresent disclosure.

Referring to FIGS. 9, 12-15, in some embodiments, a plurality ofrepeated first-category pixel groups 10′ are arranged in an array. Thecenters of the first sub-pixels 11′ of each column of the first-categorypixel groups 10′ in the first pixel area L are in the same straightline. For an embodiment in which the first color is green, human eye ismore sensitive to green sub-pixels. Therefore, when the green sub-pixelsare linearly aligned along a column direction, the pixel arrangementwithin the first pixel area L can be more uniform visually. In addition,the centers of the first sub-pixels 11′ of each row of thefirst-category pixel groups 10′ can also be in a same straight line, andthe centers of the second sub-pixels 12′ and the third sub-pixels 13′can be both in a same straight line. By aligning the first sub-pixels11′ in a row direction, and aligning the second sub-pixels 12′ and thethird sub-pixels 13′ in a straight line, the white point distributionformed by the first-category pixel groups 10′ can be more uniform,thereby improving the display quality.

In FIGS. 9 and 12, the centers of the second sub-pixels 12′ of eachcolumn of the first-category pixel groups 10′ in the first pixel area Lare in a same straight line, and the centers of the third sub-pixels 13′are in a same straight line. In this way, the second color and the thirdcolor within the first pixel area L can form a vertical line with afavorable consistency along a column direction, cooperating with thatthe first sub-pixels 11′ of the first color are also aligned in thecolumn direction, thereby making the pixel arrangement of the firstpixel area L along a column direction and a row direction more uniformvisually, and further improving the display quality.

In FIGS. 9, 12-15, the centers of the first sub-pixel 11′ of each columnof the first-category pixel groups 10′ in the first pixel area L and oneof the fourth sub-pixel 21′ and the seventh sub-pixel 24′ of each columnof the second-category pixel groups 20′ in the second pixel area H arein the same straight line. For an embodiment in which the first color isgreen, human eye is more sensitive to green sub-pixels. Therefore, whenthe green sub-pixels of the first pixel area L and the second pixel areaH are linearly aligned along a column direction, the white lines withinthe first pixel area L and the second pixel area H adjacent to eachother along a column direction are more matched, so that the first pixelarea L and the second pixel area H have a relatively smaller imagechange and offset, thereby enhancing the image quality.

Referring to FIGS. 9 and 13, in some embodiments, the sub-pixels of thefirst pixel area L adjacent to the second pixel area H are the secondsub-pixel 12′ and the third sub-pixel 13′, and the sub-pixels of thesecond pixel area H adjacent to the first pixel area L are the thirdsub-pixel 13′ and the second sub-pixel 12′, so that the sub-pixels ofthe first pixel area L and the second pixel area H adjacent to eachother have different colors, thereby reducing or eliminating the colorshift risk caused by color accumulation at a boundary position of thetwo pixel areas, and enhancing the image quality.

Compared with the embodiments of FIGS. 9 and 13, the first sub-pixel 11′of the first-category pixel groups 10′ in the first pixel area L in theembodiments of FIGS. 12 and 14 is located on one side of the secondsub-pixel 12′ and the third sub-pixel 13′ adjacent to the second pixelarea H (i.e., a lower side of the second sub-pixel 12 and the thirdsub-pixel 13 in FIG. 12). This makes the sub-pixel of the first pixelarea L adjacent to the second pixel area H to be the first sub-pixel11′, and the sub-pixels of the second pixel area H adjacent to the firstpixel area L to be the second sub-pixel 12′ and the third sub-pixel 13′,so that the sub-pixels of the first pixel area L and the second pixelarea H adjacent to each other have different colors, thereby reducing oreliminating the color shift risk caused by color accumulation at aboundary position of the two pixel areas, and enhancing the imagequality, and it is also possible to synthesize a white light to avoid apurple color bleeding, thereby enhancing the image quality.

Referring to FIGS. 9, 12-14, by comparing the embodiments of FIGS. 13and 14 and the embodiments of FIGS. 9 and 12, the difference lies inthat the first-category pixel groups in odd-numbered and even-numberedrows in the first pixel area L have different arrangement manners. InFIGS. 13 and 14, the positions of the second sub-pixel 12′ and the thirdsub-pixel 13′ of the first-category pixel groups 10 a′ in theodd-numbered rows with respect to the first sub-pixel 11′ are oppositeto the positions of the second sub-pixel 12′ and the third sub-pixel 13′of the first-category pixel groups 10 b′ in the even-numbered rows. Thefirst-category pixel groups 10 a′ in the odd-numbered rows and thefirst-category pixel groups 10 b′ in the even-numbered rows are arrangedat intervals along a column direction. This pixel structure can make thefirst pixel area L form an alternating form of the second sub-pixel 12′of the second color and the third sub-pixel 13′ of the third color alonga column direction, which can reduce the color shift risk of singlecolor accumulation, thereby enhancing the image quality.

In addition, referring to FIGS. 9, 12-14, in some embodiments, thecenters of the second sub-pixels 12′ of each column of thefirst-category pixel groups 10′, 10 a′ or 10 b′ in at least partial rowsin the first pixel area L and the centers of the fifth sub-pixels 22′ ofa corresponding column of the second-category pixel groups 20′ in thesecond pixel area H are in a same straight line. In this way, the firstpixel area L and the second pixel area H can form lines of a secondcolor with relatively consistent shapes. Similarly, the centers of thethird sub-pixels 13′ of each column of the first-category pixel groups10′, 10 a′ or 10 b′ in at least partial rows in the first pixel area Land the centers of the sixth sub-pixels 23′ of a corresponding column ofthe second-category pixel groups 20′ in the second pixel area H are in asame straight line. In this way, the first pixel area L and the secondpixel area H can have a relatively smaller image change and offset,thereby improving the image quality.

Compared with the above-described embodiments shown in FIGS. 9, 12-14,referring to FIG. 15, in some embodiments, a plurality of eighthsub-pixels 25′ of the first color can be provided at positions in thesecond pixel area H adjacent to the first pixel area L. The eighthsub-pixel 25 is located between the second sub-pixel 12′ in one of everytwo adjacent columns of the first-category sub-pixel groups 10′ in thefirst pixel area and the third sub-pixel 13′ in another of every twoadjacent columns of the first-category sub-pixels 10′ in the first pixelarea. In FIG. 15, at a location where the first pixel area L is adjoinedwith the second pixel area H, the sub-pixels of the second color and thethird color are present alternately, and the sub-pixels of the secondcolor and the third color are mixed by adding the eighth sub-pixel 25′,so that it is possible to eliminate a purple color bleeding risk at theadjoining position, thereby enhancing the image quality.

The eighth sub-pixel 25′ can also be added to other embodiments. Forexample, in the embodiments of FIGS. 9 and 13, the eighth sub-pixel 25′can be disposed at a position in the second pixel area H adjacent to thefirst pixel area L, and between the second sub-pixel 12′ and the thirdsub-pixel 13′ between every two adjacent columns of the first-categorysub-pixels in the first pixel area.

In the above-described embodiments shown in FIGS. 9-15, each of thesub-pixels included in the first-category pixel groups 10′ and thesecond-category pixel groups 20′ has a same shape, such as square. Thefourth sub-pixel 21′, the fifth sub-pixel 22′, the sixth sub-pixel 23′,and the seventh sub-pixel 24′ in the second-category pixel groups 20′all have an equal area.

FIGS. 16-20 are respectively schematic pixel arranging diagramsaccording to further embodiments of the pixel arrangement structure ofthe present disclosure.

Compared with the embodiments respectively shown in FIGS. 2, 5 to 8, theembodiments respectively shown in FIGS. 16 to 20 are consistent inaspects such as the arrangement manners, colors and shapes of thesub-pixels in the first-category pixel groups 10 and the second-categorypixel groups 20, and the difference lies in that the first-categorypixel groups 10 in the first pixel area L in the embodiments shown inFIGS. 16 to 20 are arranged more sparsely, and pixel density of thefirst pixel area L is ¼ of that of the second pixel area H.

In the above-described embodiments of the arrangement structure, thefirst pixel area L can be in any direction of the second pixel area. Forexample, the second pixel area H in FIG. 1 can be on the left side, theright side and the lower side of the first pixel area L.
